Thanks for the info. I found the Lock/Logout Buttons applet. However the lock button does the same thing as Ctrl-Alt-L it just prevents input but keeps everything on my screen visible.
I think the problem might be screensaver related. I tried the "blank screen" screensaver and that did blank the screen. Testing all of the screensavers, the only ones that work are the ones not listed in a category. So anything listed undre OpenGL Screen Saver, Gadgets & Simulations, Fyling Things, Banners & Pictures, or Visit to Flatland, don't seem to work. Using the test button they seem to work fine, but when it comes to actual activation they don't. What could I be doing wrong?
Thanks
